[Suicide Junkie]

With WMGs, the general idea is to hit 'em all at once in the first turn.

If you have a Pile of WMGs, & no defence, you hope to destroy most of the enemy forces on the first turn.

If not, you have to use tight-in warships with small beam weapons & heavy shields to hold 'em off until the WMGs are recharged.

Basically, they're support weapons, "artillery" if you will, to be fired by weak ships behind your main lines.
